Divers will help researchers tag sharks, and capture and tag sea turtles as part of an ongoing project to track the movements of these endangered animals in hopes of eventually expanding protected zones. I travelled with them earlier this year (and will also be going on this March trip) and it was a fabulous experience - not only did I get to do all the regular dives Cocos is known for, I was very happy to have participated in research that will hopefully protect the creatures I love.
